The finest astronomer of his day, Polgooth studied at the Invisible
Observatory in Khazakstan before returning to teach at Hogwarts. Polgooth
detected the existence of the Hiding Planets and the Whispering Stars.
Polgooth was also a successful businessman, one of the first to capitalize
on the Frog mania of the late '20s and early '30s. The frog trade brought
Polgooth into fierce competition with his old teammate, Ashton Kilbane,
and 'at it like Ashton and Clover' became a popular description of any
battling rivals in the 1930s. When it was announced that the two firms
would merge in 1939, many believed that the news was surely a hoax;
but merge they did, creating the Kilbane and Polgooth we know today.
